I gotchu, the answer’s elastic potential energy.
Momentum is Mass × Velocity
= 1875×22 = 41250 kg m/sec
F=mxa
(25-2.6)=7 X a
22.4\7=a
a =3.2 metres per second squared
We Know, F = m*a
Here, F = 34 N
m = 213 Kg
Substitute their values in the equation,
34 = 213 * a
a = 34/213
a = 0.159 m/s²
So, your final answer & the acceleration of the object would be 0.159 m/s²
Hope this helps!
